Defence looks to serving or ex-serving foreign military personnel to fill gaps in their Services. If you are not an Australian Citizen or Permanent Resident, you may still be eligible for entry into the Australian Navy, Army or Air Force.

The Royal Australian Air Force (RAAF) provides air and space power for Australia's security. It is the youngest of the three armed Services in the Australian Defence Force (ADF) but the second-oldest air force in the world.

The Navy's role is to promote and protect Australia's interests at sea using a mix of ships, submarines and aircraft manned by highly trained and skilled personnel and equipped with appropriate sensors and weapons systems.
